Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a visual rectal drainage device. Background Technology

[0002] Anorectal drainage devices are medical care instruments used for patients with fecal incontinence or requiring bowel decompression and stool drainage. They guide stool through a drainage tube inserted into the rectum to an external collection bag. In current applications, medical staff insert the tip of the drainage tube into the patient's rectum, securing it with a balloon or strap. The stool collection bag, connected to the other end of the drainage tube, is then suspended from the side rail of the bed using hooks, and the condition of the stool is observed during the drainage process.

[0003] Although existing stool collection bags are made of transparent material, when the stool is dark in color, medical staff cannot easily distinguish whether it contains blood with the naked eye, and there is a lack of direct chemical colorimetric monitoring methods. The material at the tip of the drainage tube cannot be made rigid, and its continuous rigidity after entering the body can put pressure on and damage the mucous membrane of the body cavity. The internal fixation method makes it difficult to ensure that the outer wall of the tube fits tightly against the inner wall of the rectum, and the stool is prone to leakage.

[0004] Meanwhile, the hanging operation on the bed rails requires medical staff to manually align and fasten the hooks, making the assembly and disassembly process cumbersome. The existing hanging stress point is concentrated at the top of the stool bag, and the downward gravity of the stool bag when it is full is entirely converted into a pulling force on the top pipe interface. There is a lack of bottom support structure to distribute the stress, which can easily cause the pipe interface to loosen and fall off.

[0005] To address the aforementioned deficiencies, this invention provides a visual rectal drainage device. It combines a blood-sensitive coating with a transparent stool storage bag to provide both physical and chemical visual monitoring. It utilizes a temperature-sensitive memory material to reduce the stimulation of the tubing on the human body and uses an airbag to prevent side leakage. At the same time, it combines a suspension frame and a bottom support belt to achieve closed locking through resistance and rebound, simplifying the bed suspension operation process and transferring the gravity load of the top interface. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem solved by the present invention is that the existing anorectal drainage equipment has the following defects: it is inconvenient to monitor the bleeding of excrement, the fixation method is highly irritating to the human body cavity and is prone to side leakage of excrement, and the suspension structure is cumbersome to operate and has insufficient load-bearing stability.

[0007] To address the problems existing in the prior art, the present invention provides the following technical solution: This invention provides a visual rectal drainage device, including a drainage collection component and a suspension support component; The drainage and collection assembly includes a transparent sterile stool storage bag, a hollow connecting tube, and a temperature-sensitive memory elastic head; one end of the hollow connecting tube is spirally connected to the top interface of the sterile stool storage bag, and the other end is fixed to the temperature-sensitive memory elastic head; The suspension support assembly includes a support strap, a suspension frame, two sets of locking tongues, and two sets of return springs; the support strap is detachably sleeved on the bottom of the sterile stool storage bag, and the upper part of the support strap is connected to the suspension frame via a connecting assembly; the two sets of locking tongues are rotatably connected to both sides of the top opening of the suspension frame; the two sets of return springs are connected between the inner wall of the suspension frame and the two sets of locking tongues. When the two sets of locking tongues move upward with the suspension frame and abut against the outer guardrail crossbar, they are pressed against the elastic force of the two sets of return springs and rotate inward and downward to open. After the outer guardrail crossbar slides into the interior, it is reset by the elastic force to form a closed lock.

[0008] The system utilizes upward suspension pressure to force the two sets of locking tongues to rotate inward and open. After the outer guardrail crossbar enters the suspension frame, the elasticity of the two sets of return springs pushes the two sets of locking tongues to rotate in opposite directions to return to their original position and lock, simplifying the operation process. The transparent and visible sterile stool storage bag allows for direct observation of the excrement's condition.

[0009] Preferably, two sets of pressing blocks are fixedly installed at the bottom outer sides of the two sets of locking tongues, and the other ends of the two sets of return springs are fixedly installed on the two sets of pressing blocks. Two sets of pressing blocks are used to, when subjected to inward pressing force, link two sets of locking tongues to overcome the elastic force of two sets of return springs and rotate inward and downward to open the notch, thus releasing the locking of the suspension frame. Pressing the two sets of pressing blocks forces the two sets of locking tongues to rotate inward, realizing the disassembly of the suspension frame from the external guardrail crossbar.

[0010] Preferably, two sets of extended limiting blocks are fixedly installed on the top of the suspension frame and above the two sets of locking tongues; Two sets of extended limiting blocks are located above the rotation path of the two sets of locking tongues. They are used to prevent the two sets of locking tongues from being flipped upwards by force when locked. The two sets of extended limiting blocks restrict the flipping direction of the two sets of locking tongues and prevent the device from falling off.

[0011] Preferably, the connecting assembly consists of two sets of connecting rings and two sets of connectors. The two sets of connecting rings are fixedly installed on the top two sides of the support belt, and one end of each set of connectors is rotatably sleeved inside the two sets of connecting rings. The other end of each set of connectors is fixedly installed at the bottom of the suspension frame.

[0012] Two sets of connecting rings and two sets of connecting parts form a movable hinge to adapt to different suspension angles.

[0013] Preferably, the inner wall of the middle section of the hollow connecting hose is coated with an inductive coating; the inductive coating is an o-toluidine hemoglobin inductive color-changing coating, which has the characteristic of reacting with color when in contact with excrement containing blood.

[0014] The sensor coating changes color when it comes into contact with blood, providing visual monitoring of chemical reactions and facilitating the monitoring of gastrointestinal bleeding symptoms.

[0015] Preferably, an airbag is fixedly installed on the hollow connecting hose and behind the temperature-sensing memory elastic head; the airbag is an inflatable structure, used to fit against the inner wall of the cavity after inflation, so as to achieve non-invasive fixation of the tube.

[0016] After the air sac inflates, it adheres to the inner wall of the intestine, preventing leakage of excrement.

[0017] The airbag is equipped with an inflation end, and an inflation nozzle for connecting an external inflation device is fixedly installed on the inflation end.

[0018] Preferably, the temperature-sensitive shape memory elastic head is made of medical-grade temperature-sensitive shape memory polyurethane thermoplastic elastomer. The temperature-sensitive shape memory elastic head has the characteristic of maintaining moderate rigidity at room temperature and softening upon contact with human body temperature.

[0019] The rigid tube at room temperature facilitates insertion. Once inside the rectum, it softens due to body temperature, reducing pressure and damage to the rectal mucosa.

[0020] Preferably, the top interface of the sterile stool storage bag is provided with a threaded part that can be detachably screwed into the hollow connecting hose, and the force transmission structure formed by the support belt and the suspension frame is used to share the downward pulling force on the top interface when the sterile stool storage bag is fully loaded.

[0021] The support strap cradles the sterile stool bag from the bottom, transferring the weight load and preventing the sterile stool bag from detaching from the hollow connecting tubing due to gravity.

[0022] Preferably, the sterile stool storage bag, the hollow connecting tube, and the temperature-sensitive memory elastic head are internally interconnected, forming a coaxial and continuous excrement drainage channel.

[0023] The channel structure ensures smooth flow of waste and prevents pipe blockage.

[0024] This invention provides a visual rectal drainage device. It has the following beneficial effects: 1. This invention involves coating the inner wall of a hollow connecting tube with a blood-reflective color-sensitive coating, combined with a transparent, sterile stool storage bag. This allows medical personnel to not only directly observe the state of the excrement but also to determine the presence of blood in the excrement through the color reaction of the color-sensitive coating. This dual visual monitoring method provides an intuitive basis for monitoring gastrointestinal bleeding symptoms.

[0025] 2. This invention utilizes a temperature-sensitive memory elastic head made of medical-grade temperature-sensitive memory material, combined with an air bladder on a hollow connecting tube. This allows the temperature-sensitive memory elastic head to maintain moderate rigidity at room temperature for easy tube insertion, while softening upon contact with body temperature, reducing pressure damage to the mucous membranes of body cavities. After the air bladder inflates, it adheres to the inner wall of the cavity, preventing leakage of excrement to the outside, thus achieving non-invasive fixation of the drainage channel.

[0026] 3. This invention, by incorporating a support belt, a suspension frame, and two sets of locking tongues connected to two sets of return springs, allows the outer guardrail crossbar to slide into the suspension frame due to resistance, and the two sets of locking tongues rotate in opposite directions to reset and lock, simplifying the suspension operation. The support belt supports the sterile stool bag from the bottom, forming a force transmission structure with the suspension frame, distributing the downward pulling force on the top interface when the sterile stool bag is fully loaded, preventing the structure from detaching due to gravity.

[0027] 4. This invention, by setting an extension limiting block and a pressing block on the suspension frame, can effectively prevent the locking tongue from flipping upward in the suspended and locked state, eliminating the risk of the device accidentally falling off due to external pulling. Moreover, during disassembly, the locking tongue can be quickly unlocked by pressing the pressing block with one hand. At the same time, with the movable hinge structure composed of connecting rings and connecting parts, the suspension frame can adapt to the tilt angle of different bed rails, improving the convenience and flexibility of clinical nursing operations.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1 This invention provides a visual rectal drainage device, including a drainage collection component and a suspension support component; The drainage and collection assembly includes a transparent sterile stool collection bag 1, a hollow connecting tube 2, and a temperature-sensitive memory elastic head 4; one end of the hollow connecting tube 2 is spirally connected to the top interface of the sterile stool collection bag 1, and the other end is fixed to the temperature-sensitive memory elastic head 4; The suspension support assembly includes a support belt 7, a suspension frame 10, two sets of locking tongues 11, and two sets of return springs 14.

[0032] The sterile stool storage bag 1, the hollow connecting tube 2, and the temperature-sensitive memory elastic head 4 are internally interconnected, forming a coaxial and continuous excrement drainage channel.

[0033] In this overall architecture, the transparent and visible sterile stool bag 1 allows medical staff to directly observe the state of the excrement, and the coaxial through-channel structure ensures smooth flow of excrement and prevents blockage of the drainage tube.

[0034] Please see the appendix Figure 2 The inner wall of the middle section of the hollow connecting hose 2 is coated with an inductive coating 3. The inductive coating 3 is an o-toluidine hemoglobin inductive color-changing coating, which can quickly undergo an oxidation color reaction when in contact with excrement containing blood.

[0035] The temperature-sensitive shape memory elastic head 4 is made of medical-grade temperature-sensitive shape memory polyurethane thermoplastic elastomer. The temperature-sensitive shape memory elastic head 4 has the characteristic of maintaining moderate rigidity at room temperature and undergoing autonomous softening deformation triggered by temperature sensation after contact with human body temperature.

[0036] An airbag 5 is fixedly installed on the hollow connecting hose 2, located behind the temperature-sensitive memory elastic head 4. The airbag 5 is an inflatable structure used to fit against the inner wall of the cavity after inflation, achieving non-invasive fixation of the tubing. The airbag 5 has an inflation end, and an inflation nozzle 6 for connecting to an external inflation device is fixedly installed on the inflation end.

[0037] In this overall architecture, the sensing coating 3 changes color when it comes into contact with blood, providing visual monitoring of chemical reactions and facilitating clinical monitoring of gastrointestinal bleeding symptoms. The temperature-sensitive memory elastic head 4 is rigid at room temperature, making tube insertion convenient and smooth. Once inside the human body, it softens due to the influence of body temperature, reducing pressure and damage to the rectal mucosa. After the air bladder 5 expands, it fits against the inner wall of the cavity, preventing excrement from leaking outward.

[0038] Please see the appendix Figure 3 The top interface of the sterile stool storage bag 1 is provided with a threaded part that can be detachably screwed into the hollow connecting hose 2.

[0039] The support strap 7 is detachably attached to the bottom of the sterile stool storage bag 1.

[0040] In this overall structure, the threaded fitting provides a sealed and detachable connection between the tubing and the stool bag body, and the support strap 7 holds the sterile stool bag 1 from the bottom, transferring the gravity load and preventing the sterile stool bag 1 from detaching from the hollow connecting hose 2 due to gravity.

[0041] Please see the appendix Figure 4 The support strap 7 is connected to the suspension frame 10 via a connecting assembly. The force transmission structure formed by the support strap 7 and the suspension frame 10 is used to share the downward pulling force on the top interface when the sterile stool bag 1 is fully loaded.

[0042] The connecting assembly consists of two sets of connecting rings 8 and two sets of connectors 9. The two sets of connecting rings 8 are fixedly installed on the top two sides of the support belt 7.

[0043] In this overall architecture, the force transmission structure shares the weight of the excrement, avoiding excessive local stress that could damage interface components or cause liquid leakage.

[0044] Please see the appendix Figure 5 The two sets of connecting rings 8 are rotatably sleeved on one end of the two sets of connecting parts 9, and the other end of the two sets of connecting parts 9 is fixedly installed at the bottom of the suspension frame 10.

[0045] In this overall architecture, two sets of connecting rings 8 and two sets of connecting parts 9 form a movable hinge node, which can adapt to different suspension angles on the side of the hospital bed and improve the flexibility of the device.

[0046] Please see the appendix Figure 6 Two sets of locking tongues 11 are rotatably connected to both sides of the top opening of the suspension frame 10; two sets of return springs 14 are connected between the inner wall of the suspension frame 10 and the two sets of locking tongues 11. Two sets of pressing blocks 13 are fixedly installed at the bottom outer sides of the two sets of locking tongues 11, and the other ends of the two sets of return springs 14 are fixedly installed on the two sets of pressing blocks 13, thereby realizing the transmission connection with the two sets of locking tongues 11.

[0047] The two sets of pressing blocks 13 are used to, when subjected to inward pressing force, link the two sets of locking tongues 11 to overcome the elastic force of the two sets of return springs 14 and rotate inward and downward to open the notch and release the locking of the suspension frame 10.

[0048] Two sets of extended limiting blocks 12 are fixedly installed on the top of the suspension frame 10 and above the two sets of locking tongues 11. The two sets of extended limiting blocks 12 are located above the rotation path of the two sets of locking tongues 11 and are used to prevent the two sets of locking tongues 11 from being flipped upward by force when locked.

[0049] When the two sets of locking tongues 11 move upward with the suspension frame 10 and abut against the outer guardrail crossbar, they are pressed against the elastic force of the two sets of return springs 14 and rotate inward and downward to open. After the outer guardrail crossbar slides into the interior, it is reset by the elastic force to form a closed lock.

[0050] In this overall structure, the two sets of locking tongues 11 are forced to rotate inward and open by the upward suspension pressure. After entering the interior of the suspension frame 10, they quickly rebound to form a closed lock, which simplifies the suspension operation process. Pressing the two sets of compression blocks 13 forces the two sets of locking tongues 11 to rotate inward, realizing the quick disassembly of the device from the external guardrail crossbar. The extended limiting block 12 restricts the flipping direction of the two sets of locking tongues 11 to prevent the device from falling off in the suspension state.

[0051] Working principle: After the device is unsealed, the support belt 7 is first attached to the outer surface of the sterile stool storage bag 1, and the support belt 7 is used to support the sterile stool storage bag 1 as a whole.

[0052] Then, the bedside suspension is performed. The operator only needs to place the suspension frame 10 below the bed rail crossbar and move the suspension frame 10 upward so that the crossbar directly contacts the top surface of the two sets of locking tongues 11. After being pressed, the two sets of locking tongues 11 overcome the elastic force of the two sets of return springs 14 and rotate inward and downward to open. After the crossbar slides completely into the suspension frame 10, the return spring 14 releases its elastic force to push the squeezing block 13, so that the two sets of locking tongues 11 automatically rotate in opposite directions to reset and close, completing the one-handed quick suspension.

[0053] When the device is in the suspended and locked state, its own weight pulls it downwards. At this time, the guardrail bar will exert an upward pushing force on the locking tongue 11. However, since the extension limiting block 12 is pressed against the top of the locking tongue 11, it plays a limiting and blocking role in the upward flipping of the two sets of locking tongues 11, thereby locking the outer guardrail bar inside the suspension frame 10, ensuring that the suspension is secure and preventing accidental fall.

[0054] After proper suspension, the operator uses the temperature-sensitive memory elastic head 4, which has moderate rigidity at room temperature, to smoothly insert the temperature-sensitive memory elastic head 4 into the patient's perianal drainage position. After insertion, the operator slowly inflates the air bag 5 using an external device through the inflation nozzle 6. The air bag 5 expands and adheres to the inner wall of the cavity to achieve non-invasive fixation and prevent the tube from shifting or slipping. At this time, the temperature-sensitive memory elastic head 4 automatically softens upon contact with the body temperature, flexibly conforming to the human tissue and reducing mucosal irritation and damage.

[0055] During the drainage process, the excrement flows through the hollow connecting tube 2 through the middle detection area. If there is a trace amount of blood in the feces, it will immediately trigger the sensor coating 3 to produce a color reaction, which will directly indicate to medical staff that there is abnormal blood in the stool. Then the feces continue to flow down into the sterile stool storage bag 1 at the bottom for collection.

[0056] As the sterile stool bag 1 gradually becomes full, the support belt 7 is evenly stressed and provides stable bottom support, preventing the top threaded interface of the sterile stool bag 1 from being pulled and damaged or falling off due to excessive weight.

[0057] When it is necessary to replace the sterile stool bag 1, first untie and remove the support strap 7 from the bottom of the fully loaded sterile stool bag 1. Then, directly rotate and unscrew the fully loaded sterile stool bag 1 to replace it with a new sterile stool bag 1, and then reattach the support strap 7 to the bottom of the new sterile stool bag 1. After the drainage is completed, the gas in the deflation bag 5 can be smoothly removed from the drainage tube. When finally removing the suspension device, simply pry the two sets of compression blocks 13 by hand, which will cause the two sets of locking tongues 11 to overcome the elasticity and rotate inward and downward to open the notch, so that the suspension frame 10 can be easily unlocked and removed from the outer guardrail crossbar.

[0058] In summary, this device not only fills the technological gap in real-time monitoring of micro-bleeding during drainage, but also fundamentally eliminates the risk of unplanned tube removal and tube dislodgement that is easily caused during routine high-frequency nursing operations such as turning over and percussion of the back in critically ill patients through its adaptive angle flexible suspension and bottom pressure distribution design. It has extremely high clinical promotion value.
